,Long Term Behavior of Dynamic Equilibria in?Fluid Queuing Networks,ink pair and each link has a per-time-unit capacity and a transit time. A dynamic equilibrium (or equilibrium flow over time) is a flow pattern over time such that no flow particle has incentives to unilaterally change its path. Although the model has been around for almost fifty years, only recentl

A 4/5 - Approximation Algorithm for the Maximum Traveling Salesman Problem,ute a traveling salesman tour of maximum weight. We present a fast combinatorial . – approximation algorithm for Max TSP. The previous best approximation for this problem was .. The new algorithm is based on a technique of eliminating difficult subgraphs via gadgets with ., a new method of edge colo

Compact, Provably-Good LPs for Orienteering and Regret-Bounded Vehicle Routing,mation results for these problems. In orienteering, the goal is to find a maximum-reward .-rooted path, possibly ending at a specified node, of length at most some given budget .. In ., the goal is to find the minimum number of .-rooted paths of . at most a given bound . that cover all nodes, where

,Discrete Newton’s Algorithm for Parametric Submodular Function Minimization,r this line search problem is very natural, but no strongly polynomial bound on its number of iterations was known (Iwata .). We solve this open problem by providing a quadratic bound of . on its number of iterations. Our result considerably improves upon the only other known strongly polynomial tim
